Ofcom has reaffirmed its intention to make Openreach a more independent organisation.
BT was ordered by Ofcom in July to give Openreach more independence and investment powers, so the broadband subsidiary could be run as a distinct and legally separate company with its own board.
However, the regulator stopped short of calling for a full structural separation, saying its proposals will provide Openreach with the greatest possible degree of independence without separating the companies entirely, and lead to decisions being taken for the good of its customers and the wider telecoms industry.
Ofcom has this week reiterated its intention to redefine the relationship between BT and Openreach, telling the Telegraph it is "determined" to make the infrastructure subsidiary more independent.
This, it said, would ensure the body is "well-placed to invest in full fibre for all its customers".
"Greater separation will provide even more regulatory clarity and confidence to the industry," Ofcom continued.
